electrifyy [1] filed a request to merge gnome-osx-hsierra-gtk-theme [2] into gnome-osx-gtk-theme [3]: GNOME-OSX flavours have been deprecated, and instead been rolled into a single package [1] https://aur.archlinux.org/account/electrifyy/ [2] https://aur.archlinux.org/pkgbase/gnome-osx-hsierra-gtk-theme/ [3] https://aur.archlinux.org/pkgbase/gnome-osx-gtk-theme/
